Virginia Law

Chapter 800. Virginia Pollutant Discharge Elimination System (VPDES) General Permit Regulation for Discharges Resulting from the Application of Pesticides to Surface Waters

9VAC25-800-10. Definitions.

The words and terms used in this chapter shall have the same meanings as given in the State Water Control Law (§ 62.1-44.2 et seq. of the Code of Virginia) and the VPDES Permit Regulation (9VAC25-31), unless the context clearly indicates otherwise, except that for the purposes of this chapter:

"Action threshold" means the point at which pest populations or environmental conditions necessitate that pest control action be taken based on economic, human health, aesthetic, or other effects. An action threshold may be based on current or past environmental factors that are or have been demonstrated to be conducive to pest emergence or growth, as well as past or current pest presence. Action thresholds are those conditions that indicate both the need for control actions and the proper timing of such actions.

"Active ingredient" means any substance (or group of structurally similar substances if specified by the federal Environmental Protection Agency (EPA) that will prevent, destroy, repel, or mitigate any pest, or that functions as a plant regulator, desiccant, or defoliant within the meaning of § 2(a) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) (40 CFR 152.3). Active ingredient also means a pesticidal substance that is intended to be produced and used in a living plant, or in the produce thereof, and the genetic material necessary for the production of such a pesticidal substance (40 CFR 174.3).

"Adverse incident" means an unusual or unexpected incident that the operator observes upon inspection or of which otherwise becomes aware, in which there is evidence that:

1. A person or nontarget organism has likely been exposed to a pesticide residue; and

2. The person or nontarget organism suffered a toxic or adverse effect.

The phrase "toxic or adverse effects" includes effects that occur within surface waters on nontarget plants, fish, or wildlife that are unusual or unexpected (e.g., effects are to organisms not described on the pesticide product labels or not expected to be present) as a result of exposure to a pesticide residue and may include:

1. Distressed or dead juvenile and small fishes;

2. Washed up or floating fish;

3. Fish swimming abnormally or erratically;

4. Fish lying lethargically at water surface or in shallow water;

5. Fish that are listless or nonresponsive to disturbance;

6. Stunting, wilting, or desiccation of nontarget submerged or emergent aquatic plants; and

7. Other dead or visibly distressed nontarget aquatic or semi-aquatic organisms (amphibians, turtles, invertebrates, etc.).

The phrase "toxic or adverse effects" also includes any adverse effects to humans (e.g., skin rashes) or domesticated animals (e.g., vomiting, lethargy) that occur either from direct contact with or as a secondary effect from a discharge (e.g., sickness from consumption of plants or animals containing pesticides) to surface waters that are temporally and spatially related to exposure to a pesticide residue.

"Biological control" means organisms that can be introduced to sites, such as herbivores, predators, parasites, and hyperparasites.

"Biological pesticides" or "biopesticides" includes microbial pesticides, biochemical pesticides, and plant-incorporated protectants (PIP).

1. "Microbial pesticide" means a microbial agent intended for preventing, destroying, repelling, or mitigating any pest, or intended for use as a plant regulator, defoliant, or desiccant, that:

a. Is a eukaryotic microorganism, including protozoa, algae, and fungi;

b. Is a prokaryotic microorganism, including Eubacteria and Archaebacteria; or

c. Is a parasitically replicating microscopic element, including viruses.

2. "Biochemical pesticide" means a pesticide that:

a. Is a naturally occurring substance or structurally similar and functionally identical to a naturally occurring substance;

b. Has a history of exposure to humans and the environment demonstrating minimal toxicity, or in the case of a synthetically derived biochemical pesticide, is equivalent to a naturally occurring substance that has such a history; and

c. Has a nontoxic mode of action to the target pests.

3. "Plant-incorporated protectant" means a pesticidal substance that is intended to be produced and used in a living plant, or in the produce thereof, and the genetic material necessary for production of such a pesticidal substance. It also includes any inert ingredient contained in the plant or produce thereof.

"Board" means the State Water Control Board. When used outside the context of the promulgation of regulations, including regulations to establish general permits, "board" means the Department of Environmental Quality.

"Chemical pesticides" means all pesticides not otherwise classified as biological pesticides.

"Cultural methods" means manipulation of the habitat to increase pest mortality by making the habitat less suitable to the pest.

"Declared pest emergency situation" means an event defined by a public declaration by a federal agency, state, or local government of a pest problem determined to require control through application of a pesticide beginning less than 10 days after identification of the need for pest control. This public declaration may be based on:

1. Significant risk to human health;

2. Significant economic loss; or

3. Significant risk to:

a. Endangered species;

b. Threatened species;

c. Beneficial organisms; or

d. The environment.

"DEQ" or "department" means the Virginia Department of Environmental Quality.

"Discharge of a pollutant" means the addition of any "pollutant" or combination of pollutants to surface waters from any point source, or the addition of any pollutant or combination of pollutants to the water of the contiguous zone or the ocean from any point source.

"FIFRA" means the Federal Insecticide, Fungicide and Rodenticide Act (7 USC § 136 et seq.) as amended.

"Impaired water" or "water quality impaired water" or "water quality limited segment" means any stream segment where the water quality does not or will not meet applicable water quality standards, even after the application of technology-based effluent limitations required by §§ 301(b) and 306 of the Clean Water Act (CWA) (33 USC § 1251 et seq. as of 1987). Impaired waters include both impaired waters with approved or established TMDLs, and impaired waters for which a TMDL has not yet been approved or established.

"Inert ingredient" means any substance (or group of structurally similar substances if designated by EPA), other than an active ingredient, that is intentionally included in a pesticide product. Inert ingredient also means any substance, such as a selectable marker, other than the active ingredient, where the substance is used to confirm or ensure the presence of the active ingredient, and includes the genetic material necessary for the production of the substance, provided that genetic material is intentionally introduced into a living plant in addition to the active ingredient.

"Integrated pest management" or "IPM" means an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM uses current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.

"Label" means the written, printed, or graphic matter on, or attached to, the pesticide or device, or the immediate container thereof, and the outside container or wrapper of the retail package, if any, of the pesticide or device.

"Labeling" means all labels and other written, printed, or graphic matter:

1. Upon the pesticide or device or any of its containers or wrappers;

2. Accompanying the pesticide or device at any time; or

3. To which reference is made on the label or in literature accompanying the pesticide or device, except when accurate, nonmisleading reference is made to current official publications of the agricultural experiment station, the Virginia Polytechnic Institute and State University, the Virginia Department of Agriculture and Consumer Services, the State Board of Health, or similar federal institutions or other official agencies of the Commonwealth or other states when such states are authorized by law to conduct research in the field of pesticides.

"Mechanical or physical methods" means mechanical tools or physical alterations of the environment for pest prevention or removal.

"Minimize" means to reduce or eliminate pesticide discharges to surface waters through the use of pest management measures to the extent technologically available and economically practicable and achievable.

"Nontarget organisms" means the plant and animal hosts of the target species, the natural enemies of the target species living in the community, and other plants and animals, including vertebrates, living in or near the community that are not the target of the pesticide.

"Operator" means any person involved in the application of a pesticide that results in a discharge to surface waters that meets either or both of the following two criteria:

1. The person who has control over the financing for or the decision to perform pesticide applications that result in discharges, including the ability to modify those decisions; or

2. The person who performs the application of a pesticide or who has day-to-day control of the application (e.g., they are authorized to direct workers to carry out those activities that result in discharges to surface waters).

"Person" means an individual; a corporation; a partnership; an association; a local, state, or federal governmental body; a municipal corporation; or any other legal entity.

"Pest" means any deleterious organism that is:

1. Any vertebrate animal other than man;

2. Any invertebrate animal excluding any internal parasite of living man or other living animals;

3. Any plant growing where not wanted, and any plant part such as a root; or

4. Any bacterium, virus, or other microorganisms, except for those on or in living man or other living animals and those on or in processed food or processed animal feed, beverages, drugs (as defined by the federal Food, Drug, and Cosmetic Act at 21 USC § 321(g)(1)), and cosmetics (as defined by the federal Food, Drug, and Cosmetic Act at 21 USC § 321(i)).

Any organism classified by state or federal law or regulation as endangered or threatened shall not be deemed a pest for the purposes of this chapter.

"Pest management area" means the area of land, including any water, for which pest management activities covered by this permit are conducted.

"Pest management measure" means any practice used to meet the effluent limitations that comply with manufacturer specifications, industry standards, and recommended industry practices related to the application of pesticides, relevant legal requirements, and other provisions that a prudent operator would implement to reduce or eliminate pesticide discharges to surface waters.

"Pesticide" means:

1. Any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any insects, rodents, fungi, bacteria, weeds, or other forms of plant or animal life or viruses, except viruses on or in living man or other animals, which the Commissioner of Agriculture and Consumer Services shall declare to be a pest;

2. Any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant; and

3. Any substance which is intended to become an active ingredient thereof.

Pesticides that are used or applied shall only be those that are approved and registered for use by the Virginia Department of Agriculture and Consumer Services.

"Pesticide discharges to surface waters from pesticide application" means the discharges that result from the application of biological pesticides and the application of chemical pesticides that leave a residue from point sources to surface waters. In the context of this definition of pesticide discharges to surface waters from pesticide application, this does not include agricultural storm water discharges and return flows from irrigated agriculture, which are excluded by law (33 USC § 1342(l) and 33 USC § 1362(14)).

"Pesticide product" means a pesticide in the particular form (including active and inert ingredients, packaging, and labeling) in which the pesticide is, or is intended to be, distributed or sold. The term includes any physical apparatus used to deliver or apply the pesticide if distributed or sold with the pesticide.

"Pesticide research and development" means activities undertaken on a systematic basis to gain new knowledge (research) or apply research findings or other scientific knowledge for the creation of new or significantly improved products or processes (experimental development).

"Pesticide residue" for the purposes of determining whether a VPDES permit is needed for discharges to surface waters from pesticide application, means that portion of a pesticide application that has been discharged from a point source to surface waters and no longer provides pesticidal benefits. It also includes any degradates of the pesticide.

"Point source" means any discernible, confined, and discrete conveyance including any pipe, ditch, channel, tunnel, conduit, or container from which pollutants are or may be discharged. This includes biological pesticides or chemical pesticides that leave a residue coming from a container or nozzle of a pesticide application device. This term does not include return flows from irrigated agriculture or agricultural stormwater run-off.

"Pollutant" means biological pesticides and any pesticide residue resulting from use of a chemical pesticide.

"Surface waters" means:

1. All waters that are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters that are subject to the ebb and flow of the tide;

2. All interstate waters, including interstate wetlands;

3. All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds the use, degradation, or destruction of which would affect or could affect interstate or foreign commerce including any such waters:

a. That are or could be used by interstate or foreign travelers for recreational or other purposes;

b. From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or

c. That are used or could be used for industrial purposes by industries in interstate commerce;

4. All impoundments of waters otherwise defined as surface waters under this definition;

5. Tributaries of waters identified in subdivisions 1 through 4 of this definition;

6. The territorial sea; and

7. Wetlands adjacent to waters, other than waters that are themselves wetlands, identified in subdivisions 1 through 6 of this definition.

Surface waters do not include wastewater treatment systems, including treatment ponds or lagoons designed to meet the requirements of the Clean Water Act (CWA) and the law. Surface waters do not include prior converted cropland. Notwithstanding the determination of an area's status as prior converted cropland by any other agency, for the purposes of the CWA, the final authority regarding the CWA jurisdiction remains with EPA.

"Target pest" means the organism toward which pest management measures are being directed.

"Total maximum daily load" or "TMDL" means a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL includes wasteload allocations (WLAs) for point source discharges, and load allocations (LAs) for nonpoint sources or natural background or both, and must include a margin of safety (MOS) and account for seasonal variations.

"Treatment area" means the area of land including any waters, or the linear distance along water or water's edge, to which pesticides are being applied. Multiple treatment areas may be located within a single pest management area.

Treatment area includes the entire area, whether over land or water, where the pesticide application is intended to provide pesticidal benefits. In some instances, the treatment area will be larger than the area where pesticides are actually applied. For example, the treatment area for a stationary drip treatment into a canal should be calculated by multiplying the width of the canal by the length over which the pesticide is intended to control weeds. The treatment area for a lake or marine area is the water surface area where the application is intended to provide pesticidal benefits.

Treatment area calculations for pesticide applications that occur at water's edge, where the discharge of pesticides directly to waters is unavoidable, are determined by the linear distance over which pesticides are applied.

"VDACS" means the Virginia Department of Agriculture and Consumer Services. VDACS administers the provisions of Virginia's pesticide statute, Chapter 39 (§ 3.2-3900 et seq.) of Title 3.2 of the Code of Virginia, as well as the regulations promulgated by the Virginia Pesticide Control Board. VDACS also has delegated authority to enforce the provisions of FIFRA. As such, VDACS is the primary agency for the regulatory oversight of pesticides in the Commonwealth.

"Wetlands" means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.

9VAC25-800-30. Authorization to discharge.

A. Any operator that meets the eligibility requirements in subsection B of this section is hereby authorized for the operator's discharges resulting from the application of pesticides to surface waters of the Commonwealth of Virginia.

The definition of operator in 9VAC25-800-10 provides that more than one person may be responsible for the same discharge resulting from pesticide application. Any operator authorized to discharge under this general permit is responsible for compliance with the terms of this permit for discharges resulting from the application of pesticides.

B. Eligibility. This permit is available to operators who discharge to surface waters from the application of (i) biological pesticides, or (ii) chemical pesticides that leave a residue (pesticides), when the pesticide application is for one of the following pesticide use patterns:

1. Mosquito and other flying insect pest control - to control public health, nuisance and other flying insect pests that develop or are present during a portion of their life cycle in or above standing or flowing water.

2. Weed and algae pest control - to control weeds, algae, and pathogens that are pests in surface waters.

3. Animal pest control - to control animal pests in surface waters.

4. Forest canopy pest control - application of a pesticide to the forest canopy to control the population of a pest species (e.g., insect or pathogen) where to target the pests effectively, a portion of the pesticide unavoidably will be applied over and deposited to surface water.

5. Intrusive vegetation pest control - to control vegetation along roads, ditches, canals, waterways, and utility rights of way where to target the intrusive pests effectively, a portion of the pesticide unavoidably will be applied over and deposited to surface water.

C. Operators applying pesticides are required to maintain a pesticide discharge management plan (PDMP) if they exceed the annual calendar year treatment area thresholds in Table 1 of this subsection:

D. An operator's discharge resulting from the application of pesticides is not authorized under this permit in the event of any of the following:

1. The operator is required to obtain an individual VPDES permit in accordance with 9VAC25-31-170 B 3 of the VPDES Permit Regulation.

2. The discharge would violate the antidegradation policy stated in 9VAC25-260-30 of the Virginia Water Quality Standards. Discharges resulting from the application of pesticides are temporary and allowable in exceptional waters (see 9VAC25-260-30 A 3 (b) (3)).

3. The operator is proposing a discharge from a pesticide application to surface waters that have been identified as impaired by that pesticide or its degradates. Impaired waters include both impaired waters with board-adopted, EPA-approved or EPA-imposed TMDLs, and impaired waters for which a TMDL has not yet been approved, established, or imposed.

If the proposed discharge would not be eligible for coverage under this permit because the surface water is listed as impaired for that specific pesticide, but the applicant has evidence that shows the water is no longer impaired, the applicant may submit this information to the department and request that coverage be allowed under this permit.

E. Discharge authorization date. Operators are not required to submit a registration statement and are authorized to discharge under this permit immediately upon the permit's effective date of March 1, 2019.

F. Compliance with this general permit constitutes compliance, for purposes of enforcement, with §§ 301, 302, 306, 307, 318, 403, and 405(a) and (b) of the federal Clean Water Act (33 USC § 1251 et seq.) and the State Water Control Law with the exceptions stated in 9VAC25-31-60 of the VPDES Permit Regulation. Approval for coverage under this VPDES general permit does not relieve any operator of the responsibility to comply with any other applicable federal, state, or local statute, ordinance, or regulation. For example, this permit does not negate the requirements under FIFRA and its implementing regulations to use registered pesticides consistent with the product's labeling. It also does not negate the requirement to fully comply with applicable state wetland program requirements administered by DEQ and the Virginia Marine Resources Commission.

G. Continuation of permit coverage.

1. Permit coverage shall expire at the end of the applicable permit term, except that the conditions of the expired pesticides general permit will continue in force for an operator until coverage is granted under a reissued pesticides general permit if the board, through no fault of the operator, does not reissue a pesticides general permit on or before the expiration date of the expiring general permit.

2. General permit coverages continued under this section remain fully effective and enforceable.

3. When the operator that was covered under the expiring or expired pesticides general permit is not in compliance with the conditions of that permit, the department may choose to do any or all of the following:

a. Initiate enforcement action based upon the pesticides general permit that has been continued;

b. Issue a notice of intent to deny coverage under a reissued pesticides general permit. If the general permit coverage is denied, the operator would then be required to cease the activities authorized by the continued general permit or be subject to enforcement action for operating without a permit;

c. Issue an individual permit with appropriate conditions; or

d. Take other actions authorized by the VPDES Permit Regulation (9VAC25-31).

GENERAL PERMIT FOR DISCHARGES RESULTING FROM THE APPLICATION OF PESTICIDES TO SURFACE WATERS OF VIRGINIA

AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA POLLUTANT DISCHARGE ELIMINATION SYSTEM AND THE VIRGINIA STATE WATER CONTROL LAW

In compliance with the provisions of the Clean Water Act (33 USC § 1251 et seq.), as amended, and pursuant to the State Water Control Law and regulations adopted pursuant thereto, operators that apply pesticides that result in a discharge to surface waters are authorized to discharge to surface waters within the boundaries of the Commonwealth of Virginia.

The authorized discharge shall be in accordance with this cover page, Part I-Effluent Limitations, Monitoring Requirements, and Special Conditions, and Part II-Conditions Applicable to All VPDES Permits, as set forth in this general permit. Coverage under this VPDES general permit does not relieve any operator of the responsibility to comply with any other applicable federal, state, or local statute, ordinance, or regulation, including the pesticide product label.

Part I

Effluent Limitations, Monitoring Requirements, and Special Conditions

A. Effluent limitations.

1. Technology-based effluent limitations. To meet the effluent limitations in this permit, the operator shall implement pest management measures that minimize discharges of pesticides to surface waters.

a. Minimize pesticide discharges to surface waters from pesticide application. All operators who perform the application of pesticides or who have day-to-day control of applications shall minimize the discharge of pollutants resulting from the application of pesticides, and:

(1) Use the lowest effective amount of pesticide product per application and optimum frequency of pesticide applications necessary to control the target pest, consistent with reducing the potential for development of pest resistance without exceeding the maximum allowable rate of the product label;

(2) No person shall apply, dispense, or use any pesticide in or through any equipment or application apparatus unless the equipment or apparatus is in sound mechanical condition and capable of satisfactory operation. All pesticide application equipment shall be properly equipped to dispense the proper amount of material. All pesticide mixing, storage, or holding tanks, whether on application equipment or not, shall be leak proof. All spray distribution systems shall be leak proof, and any pumps that these systems may have shall be capable of operating at sufficient pressure to ensure a uniform and adequate rate of pesticide application;

(3) All pesticide application equipment shall be equipped with cut-off valves and discharge orifices to enable the operator to pass over nontarget areas without contaminating them. All hoses, pumps, or other equipment used to fill pesticide handling, storage, or application equipment shall be fitted with an effective valve or device to prevent backflow into water supply systems, streams, lakes, other sources of water, or other materials. However, these backflow devices or valves are not required for separate water storage tanks used to fill pesticide application equipment by gravity systems when the fill spout, tube, or pipe is not allowed to contact or fall below the water level of the application equipment being filled, and no other possible means of establishing a back siphon or backflow exists; and

(4) Assess weather conditions (e.g., temperature, precipitation, and wind speed) in the treatment area to ensure application is consistent with product label requirements.

b. Integrated pest management (IPM) practices. The operator with control over the financing for or the decision to perform pesticide applications that result in discharges, including the ability to modify those decisions, shall to the extent practicable consider integrated pest management practices to ensure that discharges resulting from the application of pesticides to surface waters are minimized. Operators that exceed the annual treatment area thresholds established in 9VAC25-800-30 C are also required to maintain a pesticide discharge management plan (PDMP) in accordance with Part I C of this permit. The PDMP documents the operator's IPM practices.

The operator's IPM practices shall consider the following for each pesticide use pattern:

(Note: If the operator's discharge of pollutants results from the application of a pesticide that is being used solely for the purpose of "pesticide research and development," as defined in 9VAC25-800-10, the operator is only required to fully implement IPM practices to the extent that the requirements do not compromise the research design.)

(1) Mosquito and other flying insect pest control. This Part I A 1 b (1) applies to discharges resulting from the application of pesticides to control public health, nuisance and other flying insect pests that develop or are present during a portion of their life cycle in or above standing or flowing water.

(a) Identify the problem. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall consider the following for each pest management area:

(i) Identify target pests;

(ii) Establish densities for pest populations or identify environmental conditions, either current or based on historical data, to serve as action thresholds for implementing pest management measures;

(iii) Identify known breeding sites for source reduction, larval control program, and habitat management;

(iv) Analyze existing surveillance data to identify new or unidentified sources of pest problems as well as sites that have recurring pest problems; and

(v) In the event there are no data for the pest management area in the past calendar year, use other available data as appropriate to meet the conditions in Part I A 1 b (1) (a).

(b) Pest management options. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall select and implement for each pest management area efficient and effective pest management measures that minimize discharges resulting from application of pesticides to control mosquitoes or other flying insect pests. In developing these pest management measures, the operator shall evaluate the following management options, including a combination of these options, considering impact to water quality, impact to nontarget organisms, pest resistance, feasibility, and cost effectiveness:

(i) No action;

(ii) Prevention;

(iii) Mechanical or physical methods;

(iv) Cultural methods;

(v) Biological control; and

(vi) Pesticides.

(c) Pesticide use. If a pesticide is selected to manage mosquitoes or flying insect pests and application of the pesticide will result in a discharge to surface waters, the operator shall:

(i) Conduct larval or adult surveillance in an area that is representative of the pest problem or evaluate existing larval surveillance data, environmental conditions, or data from adjacent areas prior to each pesticide application to assess the pest management area and to determine when the action threshold is met;

(ii) Reduce the impact on the environment and on nontarget organisms by applying the pesticide only when the action threshold has been met;

(iii) In situations or locations where practicable and feasible for efficacious control, use larvicides as a preferred pesticide for mosquito or flying insect pest control when larval action thresholds have been met; and

(iv) In situations or locations where larvicide use is not practicable or feasible for efficacious control, use adulticides for mosquito or flying insect pest control when adult action thresholds have been met.

(2) Weed and algae pest control. This Part I A 1 b (2) applies to discharges resulting from the application of pesticides to control weeds, algae, and pathogens that are pests in surface waters.

(a) Identify the problem. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall consider the following for each pest management area:

(i) Identify target pests;

(ii) Identify areas with pest problems and characterize the extent of the problems, including, for example, water use goals not attained (e.g., wildlife habitat, fisheries, vegetation, and recreation);

(iii) Identify possible factors causing or contributing to the pest problem (e.g., nutrients, invasive species, etc.);

(iv) Establish past or present pest densities to serve as action thresholds for implementing pest management strategies; and

(v) In the event there are no data for the pest management area in the past calendar year, use other available data as appropriate to meet the conditions in Part I A 1 b (2) (a).

(b) Pest management options. Prior to the first pesticide application covered under this permit that will result in a discharge to surface waters, and at least once each calendar year thereafter prior to the first pesticide application for that calendar year, the operator shall select and implement, for each pest management area, efficient and effective pest management measures that minimize discharges resulting from application of pesticides to control pests. In developing these pest management measures, the operator shall evaluate the following management options, including a combination of these options, considering impact to water quality, impact to nontarget organisms, pest resistance, feasibility, and cost effectiveness:

(i) No action;

(ii) Prevention;

(iii) Mechanical or physical methods;

(iv) Cultural methods;

(v) Biological control; and

(vi) Pesticides.

(c) Pesticide use. If a pesticide is selected to manage pests and application of the pesticide will result in a discharge to surface waters, the operator shall:

(i) Conduct surveillance in an area that is representative of the pest problem prior to each pesticide application to assess the pest management area and to determine when the action threshold is met that necessitates the need for pest management; and

(ii) Reduce the impact on the environment and nontarget organisms by applying the pesticide only when the action threshold has been met.

(3) Animal pest control. This Part I A 1 b (3) applies to discharges resulting from the application of pesticides to control animal pests in surface waters.

2. Water quality-based effluent limitations. The operator's discharge of pollutants must be controlled as necessary to meet applicable numeric and narrative water quality standards for any discharges authorized under this permit, with compliance required upon beginning such discharge.

If at any time the operator become aware, or the department determines, that the operator's discharge of pollutants causes or contributes to an excursion of applicable water quality standards, corrective action must be taken as required in Part I D 1 of this permit.

B. Monitoring requirements.

All operators covered under this permit must conduct a visual monitoring assessment (i.e., spot checks in the area to and around where pesticides are applied) for possible and observable adverse incidents caused by application of pesticides, including the unanticipated death or distress of nontarget organisms and disruption of wildlife habitat, recreational, or municipal water use.

A visual monitoring assessment is only required during the pesticide application when feasibility and safety allow. For example, visual monitoring assessment is not required during the course of treatment when that treatment is performed in darkness as it would be infeasible to note adverse effects under these circumstances. Visual monitoring assessments of the application site must be performed:

1. During any post-application surveillance or efficacy check that the operator conducts, if surveillance or an efficacy check is conducted.

2. During any pesticide application, when considerations for safety and feasibility allow.

C. Pesticide discharge management plan (PDMP). Any operator applying pesticides and exceeding the annual application thresholds established in 9VAC25-800-30 C must prepare a PDMP for the pest management area. The plan must be kept up-to-date thereafter for the duration of coverage under this general permit, even if discharges subsequently fall below the annual application threshold levels. The operator applying pesticides shall develop a PDMP consistent with the deadline outlined in Table I-1.

The PDMP does not contain effluent limitations; the limitations are contained in Part I A 1 and A 2 of the permit. The PDMP documents how the operator will implement the effluent limitations in Part I A 1 and A 2 of the permit, including the evaluation and selection of pest management measures to meet those effluent limitations and minimize discharges. In the PDMP, the operator may incorporate by reference any procedures or plans in other documents that meet the requirements of this permit. If other documents are being relied upon by the operator to describe how compliance with the effluent limitations in this permit will be achieved, such as a pre-existing integrated pest management (IPM) plan, a copy of the portions of any documents that are being used to document the implementation of the effluent limitations shall be attached to the PDMP. The pest management measures implemented must be documented and the documentation must be kept up to date.

1. Contents of the pesticide discharge management plan. The PDMP must include the following elements:

a. Pesticide discharge management team;

b. Problem identification;

c. Pest management options evaluation;

d. Response procedures:

(1) Spill response procedures;

(2) Adverse incident response procedures; and

e. Signature requirements.

2. PDMP team. The operator shall identify all the persons (by name and contact information) who compose the team as well as each person's individual responsibilities, including:

a. Persons responsible for managing pests in relation to the pest management area;

b. Persons responsible for developing and revising the PDMP; and

c. Persons responsible for developing, revising, and implementing corrective actions and other effluent limitation requirements.

3. Problem identification. The operator shall document the following:

a. Pest problem description. Describe the pest problem at the pest management area, including identification of the target pests, sources of the pest problem, and sources of data used to identify the problem in Part I A 1 b (1) through b (5).

b. Action thresholds. Describe the action thresholds for the pest management area, including how they were determined.

c. General location map. Include a general location map that identifies the geographic boundaries of the area to which the plan applies and location of major surface waters.

4. Integrated pest management options evaluation. Operators shall document the evaluation of the pest management options, including a combination of the pest management options, to control the target pests. Pest management options include the following: no action, prevention, mechanical or physical methods, cultural methods, biological control agents, and pesticides. In the evaluation, decision makers shall consider the impact to water quality, impact to nontarget organisms, feasibility, cost effectiveness, and any relevant previous pest management measures.

5. Response procedures. Document the following procedures in the PDMP:

a. Spill response procedures. At a minimum the PDMP must have:

(1) Procedures for expeditiously stopping, containing, and cleaning up leaks, spills, and other releases to surface waters. Employees who may cause, detect, or respond to a spill or leak must be trained in these procedures and have necessary spill response equipment available. If possible, one of these individuals should be a member of the PDMP team.

(2) Procedures for notification of appropriate facility personnel, emergency response agencies, and regulatory agencies.

b. Adverse incident response procedures. At a minimum the PDMP must have:

(1) Procedures for responding to any incident resulting from pesticide applications; and

(2) Procedures for notification of the incident, both internal to the operator's agency or organization and external. Contact information for DEQ, nearest emergency medical facility, and nearest hazardous chemical responder must be in locations that are readily accessible and available.

6. PDMP signature requirements.

a. The PDMP, including changes to the PDMP to document any corrective actions taken as required by Part I D 1, and all reports submitted to the department must be signed by a person described in Part II G 1 or by a duly authorized representative of that person described in Part II G 2.

b. All other changes to the PDMP, and other compliance documentation required under this permit, must be signed and dated by the person preparing the change or documentation.

c. Any person signing documents in accordance with Part I C 6 a must include the certification from Part II G 4.

7. PDMP modifications and availability.

a. PDMP modifications. The operator shall modify the PDMP whenever necessary to address any of the triggering conditions for corrective action in Part I D 1 a, or when a change in pest control activities significantly changes the type or quantity of pollutants discharged. Changes to the PDMP must be made before the next pesticide application that results in a discharge, if practicable, or if not, as soon as possible thereafter. The revised PDMP must be signed and dated in accordance with Part II G.

The operator shall review the PDMP at a minimum once per calendar year and whenever necessary to update the pest problem identified and pest management strategies evaluated for the pest management area.

b. PDMP availability. The operator shall retain a copy of the current PDMP, along with all supporting maps and documents. The operator shall make the PDMP and supporting information available to the department upon request. The PDMP is subject to the provisions and exclusions of the Virginia Freedom of Information Act (§ 2.2-3700 et seq. of the Code of Virginia).

D. Special conditions.

b. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or

c. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this subsection, a principal executive officer of a federal agency includes (i) the chief executive officer of the agency or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit or the agency.

2. A person is a duly authorized representative only if:

a. The authorization is made in writing by a person described in subdivision 1 of this subsection;

b. The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated activity such as the position of superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matters for the company. A duly authorized representative may thus be either a named individual or any individual occupying a named position; and

c. The signed and dated written authorization is included in the PDMP. A copy of this authorization must be submitted to the department if requested.

3. All other changes to the PDMP, and other compliance documentation required under this permit, must be signed and dated by the person preparing the change or documentation.

4. Any person signing documents in accordance with subdivision 1 or 2 of this subsection must include the following certification:

"I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information contained therein. Based on my inquiry of the person or persons who manage the system or those persons directly responsible for gathering the information, the information contained is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."

H. Duty to comply. The operator shall comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the State Water Control Law and the federal Clean Water Act, except that noncompliance with certain provisions of this permit may constitute a violation of the State Water Control Law but not the Clean Water Act. Permit noncompliance is grounds for enforcement action, for permit coverage termination, or denial of permit coverage renewal.

The operator shall comply with effluent standards or prohibitions established under § 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions, even if this permit has not yet been modified to incorporate the requirement.

I. Duty to reapply. If the operator wishes to continue an activity regulated by this permit after the expiration date of this permit, the operator must have coverage under a new permit.

J. Effect of a permit. This permit does not convey any property rights in either real or personal property or any exclusive privileges. This permit does not authorize any injury to private property or invasion of personal rights, or any infringement of federal, state, or local law or regulations.

K. State law. Nothing in this permit shall be construed to preclude the institution of any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Nothing in this permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance.

L. Oil and hazardous substance liability. Nothing in this permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law.

M. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) that are installed or used by the operator to achieve compliance with the conditions of this permit. Proper operation and maintenance also include effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of backup or auxiliary facilities or similar systems that are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this permit.

N. Disposal of solids or sludges. Solids, sludges, or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering state waters.

O. Duty to mitigate. The operator shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit that has a reasonable likelihood of adversely affecting human health or the environment.

P. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.

Q. Inspection and entry. The operator shall allow the director, or an authorized representative (including an authorized contractor acting as a representative of the director), upon presentation of credentials and other documents as may be required by law, to:

1. Enter upon the operator premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this permit;

2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this permit;

3. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this permit; and

4. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as otherwise authorized by the Clean Water Act and the State Water Control Law, any substances or parameters at any location.

For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours or whenever the facility is discharging. Nothing contained in this general permit shall make an inspection unreasonable during an emergency.

R. Permit actions. Permit coverage may be terminated for cause. The filing of a request by the operator for a permit termination or a notification of planned changes or anticipated noncompliance does not stay any permit condition.

S. Transfer of permit coverage. Permits are not transferable to any person except after notice to the department. The transfer of permit coverage under this pesticide general permit is not anticipated since coverage is automatic where an operator meets the permit eligibility requirements.

T. Severability. The provisions of this permit are severable, and if any provision of this permit or the application of any provision of this permit to any circumstance is held invalid, the application of such provision to other circumstances, and the remainder of this permit, shall not be affected thereby.
